Is anyone aware of a CMIS .NET Open Source Server Side Library?

Basically I am looking for the server side of DotCMIS
If get I would need to write all implementations
Basically I want the abstract base classes that need to be implemented
I have a .NET document management application I want to add CMIS to
Not sure it matters but I am not interested in Browser Binding
Only care about AtomPub Binding Web Services Binding

Found NCMIS on CodePlex but it has not been active since 2010
